[Samba] Connection problem with 3.0.25a

[Darin]

Hello all,
   I've tried everything I can think of, I've gone through Google and 
the Samba website and I can't come up with a fix for this problem.
I've been running Samba 3 for at least the past year with no problems.  
I run a small FreeBSD 6.2 box that I use as a storage area for the 
windows XP systems on my network.  Things have been fine up until 3.0.25 
and 3.0.25a.

Now, when I try to connect to one of the shares, I get the following 
from windows:  "Y:\ refers to a location that is unavailable.  It could 
be on a hard drive on this computer or on a network. Check to make sure 
that the disk is properly inserted, or that you are connected to the 
internet or your network, and then try again.  If it still cannot be 
located, the information might have been moved to a different location."

I also get that error if I browse to the share on the network and try to 
connect that way, instead of using the mapped drive letter.

I've tried completely uninstalling 3.0.25a, removing all TDB files, 
everything and then recompile and reinstall fresh.  Any time a machine 
on the network tries to connect, the following is logged in 
/var/log/samba/log.192.168.0.216:

[2007/06/23 03:07:24, 1] smbd/service.c:make_connection_snum(1033)
  192.168.0.216 (192.168.0.216) connect to service backup$ initially as 
user nobody (uid=65534, gid=65534) (pid 63261)
[2007/06/23 03:07:34, 1] smbd/service.c:close_cnum(1230)
  192.168.0.216 (192.168.0.216) closed connection to service backup$

I'm using share level security.  I have the share set to be accessible 
by anyone on the network so that any machine has full write access.
If I remove 3.0.25a and fall back to 3.0.24, everything is fine.  I 
don't make any changes to the smb.conf file.  It just starts working 
when I go back to 3.0.24
 
Here is my smb.conf:

[global]
   workgroup = MYNET
   server string = Backup Server
   security = share
   hosts allow = 192.168.0. 127.
   log file = /var/log/samba/log.%m
   max log size = 5000
   interfaces = txp0
   dns proxy = no

[backup$]
   comment = backups
   path = /archive
   browseable = yes
   only guest = yes
   public = yes
   guest ok = yes
   writeable = yes


Any help would be greatly appreciated.

Thanks
